Asymmetrical Frame tab

In an asymmetrical frame (obtained by keeping the Apply Global Symmetry and Apply In-Bay Symmetry buttons disabled), you specify the default information in the Spans tab for the left hand rafter. Details for the right hand rafter are entered in the Asymmetrical tab as indicated below. In the row representing the appropriate rafter number, enter the rafter’s horizontal length, section size and haunch details if required. You can also swap the left and right hand rafters about using the L/R (left or right) option.
